I'm also having the same problem. I think it has something to do with the latest version of Windows (the one that auto adds Edge Chromium to your computer.) I was not having this problem before this update.<br>REPEAT BUG:<br>
Have OpenLP 2.4.2 open.
Click the "X" button in the top corner.
The "Are you sure you want to exit box pops up.
Click "Exit OpenLP".
The popup box close immediately but the rest of the program remains open.
Wait 10-15 seconds. Interacting with OpenLP or trying to click the close button again (because you thought you must have clicked cancel by mistake) crashes OpenLP.
OpenLP finally closes.
